We have performed ultrahigh-resolution angle-resolved photoemission spectroscopy on to study the band structure near the Fermi level and the Fermi surface. We found three Fermi surfaces (FS’s): two hole pockets with a dominant Pd character at the (A) point and an electron pocket with a U nature at the K (H) point. These FS’s are qualitatively well reproduced in the band structure calculation based on the localized U--electron model, while remarkable quantitative discrepancies are observed near The U states are located 0.4-1.0 eV below and do not contribute to the Fermi surface. These results indicate the strongly localized nature of U electrons in.
